실험 절차

2-Chloro-N-(4-(chlorodifluoromethoxy)phenyl)-5′-fluoro-[3,3′-bipyridine]-5-carboxamide (Stage 266.1, 70 mg, 0.160 mmol) and DIPEA (0.196 mL, 1.121 mmol) were added to a vial containing iPrOH (1 mL) and trans-4-methoxypyrrolidin-3-amine dihydrochloride (Stage 284.1, 32.5 mg, 0.168 mmol) was added under argon atmosphere. The RM was stirred at 110° C. for 40 h. The RM was treated with sat. aq. Na2CO3 (20 mL) and extracted with EtOAc. The combined extracts were washed with brine (10 mL), dried over Na2SO4, filtered and the filtrate was evaporated off under reduced pressure to give the crude product which was purified by preparative HPLC (Condition 14). Fractions containing product were treated with sat. aq. Na2CO3 and the MeCN was evaporated off under reduced pressure. The aq. phase was extracted with EtOAc. The combined organic layers were dried over Na2SO4, filtered and the filtrate was evaporated off under reduced pressure to give a residue which was suspended in DCM/n-hexane. The obtained solid was filtered off, washed with n-hexane and dried to afford the title product as a white solid. HPLC (Condition 10) tR=6.11 min, UPLC-MS (Condition 3) tR=0.86 min, m/z=508.2/510.1 [M+H]+; 1H-NMR (400 MHz, DMSO-d6) δ ppm 1.63 (br. s, 2H) 2.83-2.90 (m, 1H) 3.03-3.11 (m, 1H) 3.20-3.22 (m, 3H) 3.27-3.35 (m, 2H) 3.48-3.56 (m, 2H) 7.34 (d, J=8.21 Hz, 2H) 7.80-7.90 (m, 3H) 8.08 (d, J=2.35 Hz, 1H) 8.51 (s, 1H) 8.60 (d, J=2.74 Hz, 1H) 8.75-8.80 (m, 1H) 10.18 (s, 1H).
